The ARK os well made solid and robust, sound quality was excellent. BUT a big BUT. I used AKG studio K702 listening through the different virtual speakers was good, was able to hear sound difference in all but quite honestly, I didn’t hear much difference from bypass and the ARC, nothing sprung out at me, like having to make any changes to my mix, so me thinks another useless, maybe if not so good quality headphones used, might have the wowa factor but if you are using £300 Studio monitor flat response phones, don’t waste your money. I was expecting to be wow thing.
